Using npm behind corporate proxy .pac

Question

I need to download several packages through npm but our corporate proxy configuration is a .pac file (i'm on windows)

I have already tried

npm config set proxy http://mydomain\username:password@1.2.3.4:8181/proxy.pac
npm config set https-proxy http://mydomain\username:password@1.2.3.4:8181/proxy.pac

or

npm config set proxy http://1.2.3.4:8181/proxy.pac
npm config set https-proxy http://1.2.3.4:8181/proxy.pac

but it doesn't work...

any suggestion? thanks

Answer 1

You must use "npm config set http-proxy"

use:

npm config set http-proxy http://1.2.3.4:8181
npm config set https-proxy http://1.2.3.4:8181

At work we use ZScaler as our proxy. The only way I was able to get npm to work was to use Cntlm.

See this answer:

Answer 3

I had a similar issue and I tried all the workarounds above but none of them worked for me ( I was using special characters (like '@' symbol) in my password and I also needed to add domain name).

Apart from that I was bit apprehensive to add my password as plain text. It turned-out the easiest solution to overcome all these challenges was to use some sort of reverse proxy (like Fiddler).

I have already detailed the configuration steps in this answer in SO.

Answer 4

The NPM proxy setup mentioned in the accepted answer solve the problem, but as you can see in this npm issue, some dependencies uses GIT and that makes the git proxy setup needed, and can be done as follow:

git config --global http.proxy http://username:password@host:port
git config --global https.proxy http://username:password@host:port

The NPM proxy setup mentioned:

npm config set proxy "http://username:password@host:port"
npm config set https-proxy "http://username:password@host:port"
npm config set strict-ssl false
npm config set registry "http://registry.npmjs.org/"

Answer 5

From a little search on google the first thing I tried was this

npm config set registry http://registry.npmjs.org/
npm config set proxy "your proxy"
npm config set https-proxy "your proxy"

But still npm seemed to lose connection when trying to do "npm install"s. then I ran this line in command prompt and now I can use npm install

set NODE_TLS_REJECT_UNAUTHORIZED=0

Try this, Set proxy in npm as follows

npm config set proxy "http://<user-name>:<password>@<proxy-url>:<port>"
npm config set https-proxy "http://<user-name>:<password>@<proxy-url>:<port>"
npm config set strict-ssl false
npm config set registry "http://registry.npmjs.org/"
